CORN-PLANUNG MACHINE.

Specification of Letters Patent.

Patentedan.- 29 `1.9.07- i Application led May 18,1906. SerielNo. 317,648.

The object of the invention is yto provide an improved checking mechanism to insure a positive check, together with other novel features of construction to be hereinafter described and claimed.

ln the accompanying drawings, Figure 1 is a plan view with the seedcans yor hoppers removed. Fig. 2 is a side elevation. Fig. 3 is a sectional view of the seed-can. Fig. 4 is a plan view of the dropping-plate. Fig. 5 is a bottom view of the seed-can, and Fig. 6 is a sectional elevation of a drilling attachment.

Referring specifically to the drawings, the drive-wheelsP of the machine :have each a clutch-hub 14, engageable with clutch-col-` lars 13 on the axle A, which are held in engagement with said hubs 14 by a spring 12. The collars 13 are slid able lengthwise onthe axle, but are fastened by keys 11, so as to turn therewith. Collars S, fastened to the axle by set-screws 40, serve to properly space the wheels on the axle. 1

The frame of the machine comprises longitudinal side bars 29, mounted on the axle A. At or about the middle the side bars are connected by a cross-bar 5, and at their front ends they are connected by clevises 39 toA a cross-bar 15, V,the clevises being secured to the latter bar by bolts 38. The rear ends of the side bars are connected by a cross-bar K. The seat m is supported on a curved standard a, extending from the cross-bar 5. Lateral braces for the seat are indicated at n.

The tongue 48 extends above the bar 15, and under said tongue is a casting 36, which is fastened -at its front end to the bar 15, and to the rear end of the casting is secured a cross-bar 17. The tongue is secured to the bar 17 by a bolt 46. The front end of the casting 36 forms a clip 32 for securing, the tongue to the bar 15. Lateral braces 31 extend from the tongue and are fastened tothe bar 15 by the bolts 38.

The furrow-openers 42 are carried by brackets 28, secured at their front ends to the bar 15 and at .their rear ends to the bar 17. The furrow-openers .can .be raised or lowered, laccording to the depth it ,is desired to plant. lThis Iisdone by a foot-lever v51, pivoted `at 55 to the .standard z. To the front endof the y:foot-lever is secured one end of a spring.34,-wh1ich is fastened at ,its opposite end tothe rear end 35 of the casting 36. A hand-lever `50, having thesame pivot as the foot-lever5z1, :is connected tothe latter by a link 53.k The hand-lever is locked by a latch v54, engagea'ble with a` segment-rack 52., secured on thexpivot '55, andzto the standard .e at 56. 'The furrow-openers are wider at their rear ends ,than in `.front,.and `they are directly in front ofthe drive-wheels- The latter have al concave tread, vso that when passing over the ground .the soil iscrowded tothe center tocover the seed.

Theiseed canorhopperhas atop fb, a'bottom n', and a cover a. 'Thetop and bottom are connected by 1bolts.e and c. Secured to the bottom lrtis thefrotatable.droppingfplate i, and fitting. on the. bottom of said plate vis the bottom plate cfhaving a spout y', which when theseed-can is inposition onthe machine communicates ,withthe seed-,tube 45. The .seed-can has adepending pin g, .which is extended intoa slot 27 -in the-top ofthe bracket28, and also a hook F, engageablel withan eye f19 onthe cross-bar 15, whereby the can .is mounted on the machine. yThe dropping-plate has the usual circle of openings through which the seed drops into the spout y' when the plate is rotated. The plate also has radially-projecting fingers p for a purpose to be hereinafter described. On the inside of the seed-can is a downwardly-slant ing plate Z, extendingfrom the back of the can to the center and forming a slide and a cut-off for the seed.

At 16 is indicated a transverse shaft which is supported in the brackets 28 and secured against lengthwise movement by collars 18. To the shaft is fastened a sprocket-wheel 33, which is connected by a chain 4 to a sprocketwheel R, which is loose on the axle A. A suitable chain-tightener 1 is provided. The sprocket R has a clutch-hub which'is pressed by a spring o into engagement with a clutchcollar u, fastened to the axle by a set-screw 41. The spring o is coiled around the axis between the sprocket R and a collar t, secured to the axle. The collar t also serves to IOO lan opening in the bar 15.

prevent lengthwise movement of the axle. A suitable device g is provided for separating the clutch members and throwing the ma* chine out of gear.

On the shaft 16 is secured a trip 22, which is positioned so as to strike the ngers 2), projecting from the dropping-plate @when the shaft is rotated, thereby rotating the plate and bringing its openings successively over the spout y', through which the seed is discharged into the seed-tube 45. The lower end 43 of the tube is closed by a pivoted gate 25, which is opened at intervals to permit the seed to drop into the furrow. The gate is connected to the rear end of a longitudinal slide-bar 20, which is supported by the crossbars and 17. On the hub of the trip 22 is -a catch 49, engageable with a hoolobar 24, pivoted on one side of the slide-bar 20. When the shaft 16 is rotated, the catch 49 engages the hook-bar 24, thus pulling the bar 20 forwardly, which by reason ofv its connection with gate causes the latter to open to drop the seed into the furrow.' Vhen the catch is released, the slide-bar ispulled rearwardly to close the gate by a spring 21, coiled around a rod 44, extending from said bar and through Said rod also serves as a guide for the slide-bar.l A. spring 23 is also employed for holding the hook-bar 24 in engagement with the catch 49, thus insuring a positive catch.

From the foregoing description it will be seen that when the machine is driven across the field the* shaft 16 will be rotated from the axle A by the sprockets 33 and R and the chain 4, 'which operates the dropping-plate and the gate on the seed-tu`be to drop the seed into the furrow at regular intervals.

Journaled in boxes 47 at the rear. ends of the bars 29 is a shaft I, which carries mudf scrapers J. The Scrapers are brought into contact with the wheels by pressure on a footlever x, which is connected by a rod y to a crank-arm w on the shaft I.

The marker-shoe C is carried by a stem B, secured to the machine by a clevis D, connected to a swiveling clevis E, carried by the bar K. At the rear ends of the bars 29 are hooks H, in which the marker-stem is supported when in use. The marker can be changed from one side of the machine to the other without the operator leaving his seat by means of a rod secured to the stem B and having a grip O. This rod extends to a convenient position beside the seat m. Vhen the marker is not in use, it can be elevated by placing the grip o in a hook L, extending from the rear end of the standard 2 below the seat.

In Fig. 6 is illustrated a drilling attach ment, in which t is a dropping-plate, having on its under side gear-teeth which mesh with a pinion D, adapted to be placedon the shaft 16, the check-row mechanism heretofore described being irst removed.

I claim- 1. In a corn-planter, a seed-tube having a pivoted gate at its lower end, a slide-bar having a connection with the gate, a hook pivoted to' the slide-bar, and a wheeldriven shaft having a catch engageable with the hook for actuating the slide-bar to open the gate.

2. In a corn-planter, a wheel-driven shaft having a hub thereon provided with a projecting'trip and a catch, a rotatable dropping-plate having projecting fingers engageable bythe trip, a seed-tube having a pivoted gate at its lower end, a slidebar having a connection with the gate, and a hook pivoted to the slide-bar and engageable by the aforesaid catch.
